3 🛠️ Application Guide
3.1 Recommended Application Fields
Water slurry of cerium oxide polishing powder
Water slurry of alumina polishing powder
Water slurry of mixed polishing powder
Polishing paste
Note: Toynol® DS-1715 is suitable for dispersion and stability of low viscosity slurry, e.g. Al₂O₃ polishing slurry.
3.2 Usage Methods and Recommended Dosage
3.2.1 Recommended Dosage
When dispersing polishing powder: 20-25% (based on polishing powder, calculated by dispersant solid content SOP)
3.2.2 Operation Guidance
Do not add wetting agents separately; Toynol® wetting agents can accelerate original powder wetting.
Adding Toynol® defoamers can quickly eliminate grinding foam.
To obtain optimal performance, Toynol® additives must be added to water before resin and pigment.
It is advisable to conduct gradient tests to determine the optimal dosage.
3.2.3 Grinding Operation
Equipment: Dispersing sand mill
Grinding Media: Glass bead (0.8-1.2mm), filling rate 70%
Parameters: 3000rmp/min for 60min
3.2.4 Performance Evaluation
Viscosity evaluation: Use Brookfield rotational viscometer
Fineness measure: Scraper fineness meter
Viscosity stability: Store millbase in 100ml scale tube at 40℃ for 24 hours to observe layering scale; continue storing for 15 days to observe layering scale.
